Hoklartherm | Retractable Shade Cloth Curtains for Janssens Modern Greenhouses 10ft long, White Aluminized

Shade cloth curtains are an optimal solution for greenhouses. Especially in greenhouses with garden glass or ISO safety glass, shading is absolutely necessary to prevent "burning" on your plants from too much direct sunlight. These nice high quality self-retracting/roll-up white aluminized shade cloth curtains filter out excess sunlight, reducing heat on hot summer days. Lower inside temperatures help protect your special plants and create a cooler environment for your entertaining. Shading value is 55-60%.

These Hoklartherm shade curtains fit the Janssens Modern greenhouses, Models M23-Modern, M34-Modern, and M36-Modern, and may also fit other greenhouses. A roller blind is mounted in the housing/shade ready to be pulled out. The roller blind housing is fastened at eave height (for wall shades) or on the roof ridge (for roof shades) using brackets and screws, hanging chains, etc. Both the roof and wall roller blind can be pulled out and attached to the corresponding frame profile of the greenhouse using the screw hooks supplied. Note: The available pull out length of the shade cloth fabric is 8'6" - rolls should not be used in applications longer than 8'6". The fabric length is 10 feet, however several wraps of fabric remaining on the roll are neccesary to maintain tension on the fabric attachment point.

The roof curtains are single-roll units. Each roll is 10 feet of shade cloth (8'6" usable length) with aluminum weave, in 59" width. For the most roof coverage, you will need 2 for the M23, 3 for the M34, or 4 for the M36.

See this YouTube video for an introduction to the shade clothes.

The special Hoklartherm shading fabric is a white acrylic weave with a high aluminum content, making it highly reflective. Solar radiation is reflected by the fabric and thus not converted into heat (reflection principle, roughly corresponds to that of a mirror - no heat is generated on a mirror; in contrast, a black background gets really hot). The opinion is often expressed that interior shading is not effective and that exterior shading is therefore preferable. This is only partially true, the right shading material - light/white with a large amount of silver, moisture-resistant, UV-stable, dirt-repellent - is crucial.

Please look over this FAQ and ordering guide before ordering the shades. This will help you determine exactly which combination of shades you need to order for your greenhouse.

Shading should be installed before the plants in the greenhouse have grown too large. The sun can heat up your greenhouse quite a bit. If the temperatures rise too high, the plants practically curl up. This is how they try to brave the heat. However, this severely limits plant growth. A bad harvest or even a complete crop failure is imminent. Interior shading can help here. Although the interior shading still lets the sunlight through the greenhouse panes, it gives the plants enough shade and thus lowers the greenhouse interior temperature. Importantly, the heat must escape through appropriate ventilation options - greenhouse windows, doors, exhaust fans.

All large production greenhouses have automatic interior shading with this type of shading fabric! Advantage: The shading is not exposed to the weather (wind and rain). This helps create a pleasant and growth-friendly climate in the greenhouse. Build and trust in our many years of experience!
